2014-2020年连云港市脑卒中发病趋势分析

Trends in incidence of stroke in Lianyungang City from 2014 to 2020

目的了解2014—2020年江苏省连云港市脑卒中发病水平及变化趋势,为开展脑卒中防控提供依据。方法通过连云港市心脑血管疾病监测系统收集2014—2020年连云港市脑卒中发病资料。计算发病率并采用2010年全国第六次人口普查数据进行标化。采用平均年度变化百分比(AAPC)分析该地区脑卒中发病趋势;描述不同性别、年龄、城乡和疾病类型的发病率及变化趋势。结果2014—2020年连云港市脑卒中发病162423例,年均粗发病率为435.32/10万,标化发病率为357.28/10万,均呈上升趋势,AAPC值分别为12.61%和9.91%(t=39.098、6.123,均P<0.001)。男性脑卒中标化发病率为389.63/10万,高于女性的327.17/10万(χ^(2)=4.056,P=0.044)。脑卒中粗发病率随居民年龄增长呈上升趋势(χ^(2)趋势=258.219,P<0.001);<35岁、35~<65岁和≥65岁脑卒中粗发病率均呈逐年上升趋势,AAPC值分别为22.52%、9.78%和10.24%(t=6.723、7.867、5.156,均P<0.001)。农村脑卒中粗发病率为437.72/10万,高于城市的425.31/10万(χ^(2)=20.709,P<0.001)。疾病类型以缺血性脑卒中最多,139680例占86.00%,粗发病率和标化发病率均呈逐年上升趋势,AAPC值分别为13.79%和10.88%(t=16.865、5.128,均P<0.001)。结论2014—2020年连云港市脑卒中发病率呈上升趋势,男性、中老年人群和农村居民是脑卒中防治的重点。

Objective To investigate the incidence and trends in incidence of stroke among residents in Lianyungang City,Jiangsu Province from 2014 to 2020,so as to provide insights into stroke control.Methods The stroke morbidity data in Lianyungang City from 2014 to 2020 were captured from Lianyungang Municipal System for Monitoring of Cardiovascular and Cerebrovascular Diseases,and standardized by the sixth national population census data in China in 2010.The trends in stroke incidence were evaluated using average annual percentage change(AAPC),and the gender-,age-,region-and disease type-specific incidence and trends in incidence of stroke were descriptively analyzed.Results Totally 162423 new stroke cases were diagnosed in Lianyungang City from 2014 to 2020 new case,and the annual mean crude and standardized incidence rates were 435.32/105 and 357.28/105,which both appeared a tendency towards a rise(AAPC=12.61%,t=39.098,P<0.001;AAPC=9.91%,t=6.123,P<0.001).The standardized incidence of stroke was significantly higher in men than in women(389.63/105 vs.327.17/105;χ2=4.056,P=0.044).The crude incidence of stroke appeared a tendency towards a rise with age among residents(χ^(2)_(trend)=258.219,P<0.001),and appeared a tendency towards a rise among residents at ages of<35(AAPC=22.52%,t=6.723,P<0.001),35 to 64(AAPC=9.78%,t=7.867,P<0.001)and 65 years and older(AAPC=10.24%,t=5.156,P<0.001).The crude incidence was higher in rural areas than in urban areas(437.72/105 vs.425.31/105;χ2=20.709,P<0.001).Ischemic stroke was the predominant type(139680 cases,86.00%of all cases),and both the crude and standardized incidence appeared a tendency towards a rise(AAPC=13.79%,t=16.865,P<0.001;AAPC=10.88%,t=5.128,P<0.001).Conclusion The incidence of stroke appeared a tendency towards a rise among residents living in Lianyungang City from 2014 to 2020.Men,middle-age and elderly residents and rural residents are high-risk populations for stroke control.
